Researchers develop a way to 'turn on' REM

Headline is a bit sensationalist, dreams are not guaranteed but it's easy to see applications of this. The first thing that comes to mind is not having to bother with waking up after ~six hours to WILD, but rather do it at the start of the night, assuming hormone levels etc don't affect the dreams themselves? I've forgotten but I'm rambling so [/post]

Who would have thought that the medulla--a primordial region of the brain--is associated with the activation of REM sleep? But I guess cerebral interconnectedness shouldn't surprise us. The reasons for the development of REM are undoubtedly pertinent to the evolution of mammals. (Mice are very similar to us anyway.)

I also found the following passage interesting:

'The researchers also found that activating these brain cells while the mice were awake had no effect on wakefulness, but did make them eat more. In normal mice, these neurons — a subset of nerve cells that release the neurotransmitter gamma-amino butyric acid (GABA), and so are called GABAergic neurons — are most active during waking periods when the mice are eating or grooming, two highly pleasurable activities.'

No wonder people eat sometimes eat for comfort when they feel stressed and I'm beginning to understand why lucid dreaming can be so plesurable, too--hence the 'buzz' upon awakening. 8-)
